Method and system for generating timed events in a radio frame in an E-UTRA/LTE UE receiver

A wireless device, comprising:

• a radio frequency (RF) receiver configured to receive an RF signal, the RF signal including a primary synchronization sequence (PSS) and a secondary synchronization sequence (SSS), and to convert the signal to a baseband signal;
• and
• a baseband receiver configured to sample the baseband signal according to a sampling frequency and a downsampling frequency,
• wherein the baseband receiver is further configured to determine a timing parameter corresponding to the RF signal utilizing the downsampling frequency, the downsampling frequency being less than the sampling frequency by a decimation factor selected based on a bandwidth of the RF signal, and
• wherein the timing parameter comprises:
• PSS symbol timing;
• SSS symbol timing;
• OFDM symbol timing;
• sub-frame timing;
• half-frame timing;
• or
• frame timing of the RF signal.

In a wireless device, a method comprising:

• receiving a signal, the signal including a primary synchronization sequence (PSS) and a secondary synchronization sequence (SSS);
• converting the signal to a baseband signal;
• sampling the baseband signal at a sampling rate proportional to a system clock;
• determining a count of samples of the system clock;
• correlating the count to provide correlation values;
• accumulating the correlation values to provide accumulated correlation values;
• calculating correlation peaks based on the accumulated correlation values;
• generating a plurality of symbol timing hypotheses based on the correlation peaks;
• and
• determining symbol timing based on the plurality of symbol timing hypotheses.
